Thay were all main dealer valves. I still think its something to do whit oil presur because it gets wet whit oil on the down pipe of turbo and manafold. It don 2 turbos so far and have it rebuilt for the 2 time. Should I put a oil restricter on it from 3mm down to 1.5 or will it be to small for oil feed for turbo.

Do you got a gasket between the turbo and return to the sump ? There the manifold and so is wet or is it restricted and the oil cannot go any were ?
Also good to ask is if there was a special ring put on the shaft of the turbo to stop leakage on high boost ( done on rallye turbo's ) there I had this on my stage 2 , reduced oil consumption also

John ,
I think high pressure oil pumps are proving to be more trouble than they are worth, even the proper cosworth ones are giving trouble from what I'm hearing.are you using genuine filters as well.what brands the oil pump and matched to block type 205/200???
For ref what idle pressures you seeing hot/cold ??
